As some embodiments of the present application, all positioning holes 32 are blind holes.

[0044] By making the positioning holes 32 and the positioning posts 31 both multiple and corresponding to each other one by one, the stable and precise positioning and cooperation between the intercooler 10 and the humidifier 20 can be achieved. By making at least some of the multiple positioning holes 32 be through holes or at least some of the positioning holes 32 be blind holes, the form of the positioning holes 32 can be selected according to the actual situation, which can reduce the processing difficulty and is beneficial to improving the processing efficiency.
